Abstract
The dielectric properties of Pb1 − x Ge x Te(Ga) (x = 0.02, 0.03, 0.05) were studied in the temperature range 77–150 K at frequencies of 104–106 Hz. It is revealed that the ferroelectric phase transition temperature T c and the permittivity ɛ of Pb1 − x Ge x Te(Ga) increase substantially with the Ge content. The temperature dependence of the permittivity of Pb1 − x Ge x Te shows two peaks; the main peak is at the ferroelectric phase transition temperature T c , and an additional peak is at T 1 > T c .
